Adaptive Channel Equalization for Nonlinear Channels using Signed Regressor F...IDES Editor
Wireless communication systems are affected by
inter-symbol interference (ISI), co-channel interference in
the presence of additive white Gaussian noise. ISI is primarily
due to the distortion caused by frequency and time selectivity
of the fading channel and it causes performance degradation.
Equalization techniques are used to mitigate the effect of ISI
and noise for better demodulation. This paper presents a novel
technique for channel equalization. Here a Signed Regressor
adaptive algorithm based on FLANN (Functional Link Artificial
Neural Network) has been developed for nonlinear channel
equalization along with the analysis of MSE and BER. The
results are compared with the conventional adaptive LMS
algorithm based FLANN model. The Signed Regressor FLANN
shows better performance as compared to LMS based FLANN.
The equalizer presented shows considerable performance
compared to the other adaptive structure for both the linear
and non-linear models in terms of convergence rate, MSE
and BER over a wide range.

Analysis and Design of CMOS Source Followers and Super Source FollowerIDES Editor
The source follower circuit is used as a voltage
buffer and level shifter. It is more flexible level shifter as the
dc value of voltage level can be adjusted by changing aspect
ratio of MOSFETs. It is desired to have low output resistance
for such applications. Source follower can give minimum
output resistance 1/(gm+gmb) with load resistance and channel
resistance tending to infinity. The super source follower is a
circuit formed using negative feedback through another
MOSFET. This offers even reduced output resistance but with
reduced voltage gain as that of source follower.

Speed and Torque Control of Mechanically Coupled Permanent Magnet Direct Curr...IDES Editor
A new controller is designed for speed and torque
control of a Permanent Magnet DC motor based on
measurements of speed and current. This research work
focuses on investigating the effects of control of the speed and
torque of two brushless dc motors that are mechanically
coupled. Two controller design methods: the Root Locus
method and Bode Plot method as well as two controllers:
Proportional-Integral-Derivative (PID) and Proportional-
Integral (PI) are used to obtain the control objectives of speed
control and torque control. The simulation is performed using
MATLAB/SIMULINK software. The effects of varying the
controller gains on the system performance is studied and
quantified. The simulation results show that the speed control
objectives of the motor are satisfied even in the case of torque
disturbance from the other motor.
The document provides tips for finding an audience and engaging students as a faculty leader. It suggests surveying the student landscape, talking to different student groups and classes, using social media, celebrating students through special events, recruiting guest speakers, offering field trips and summer jobs, and putting together a plan that provides structure but is also flexible. The overall goal is to build connections, tell great stories, and have fun engaging students.

CASE ANALYSIS ON ESTIMATION OF DEMAND FOR ORANGES BY MARKET ...Harish Manchala
This document analyzes a market experiment conducted in Grand Rapids, Michigan over 31 days to estimate demand for three types of oranges - Florida Indian River, Florida interior, and California oranges. The experiment involved changing prices within a range of 16 cents across 9 supermarkets to determine price elasticity and cross-price elasticity. Analysis found the price elasticity for Florida Indian River oranges was -3.07, indicating demand was highly responsive to price changes. Cross-price elasticity between the two Florida varieties was above 1, showing they were close substitutes, whereas demand for California oranges was relatively unaffected by prices of the Florida varieties.

Optimal and Power Aware BIST for Delay Testing of System-On-ChipIDES Editor
Test engineering for fault tolerant VLSI systems is
encumbered with optimization requisites for hardware
overhead, test power and test time. The high level quality of
these complex high-speed VLSI circuits can be assured only
through delay testing, which involves checking for accurate
temporal behavior. In the present paper, a data-path based
built-in test pattern generator (TPG) that generates iterative
pseudo-exhaustive two-patterns (IPET) for parallel delay
testing of modules with different input cone capacities is
implemented. Further, in the present study a CMOS
implementation of low power architecture (LPA) for scan based
built-in self test (BIST) for delay testing and combinational
testing is carried out. This reduces test power dissipation in
the circuit under test (CUT). Experimental results and
comparisons with pre-existing methods prove the reduction
in hardware overhead and test-time.
This paper proposes the use of Embedded EZ-source
inverter system (EZSI) as a single stage power conversion
concept for adjustable speed drives (ASD) in photovoltaic
applications. Open loop and closed loop control strategy of
EZSI system are proposed. EZSI produces the same voltage
gain as Z-source inverter (ZSI) but due to the DC sources
embedded within the X- shaped impedance network, it has
the added advantage of inherent source filtering capability
and also reduced capacitor sizing. This is attained without
any extra passive filters. By controlling the shoot-through
duty ratio and modulation index, EZSI system can produce
any desired AC output voltage even greater than DC rail
voltage and it also provides ride-through capability under
voltage sag. These advantages are more significant for
adjustable speed drive (ASD) applications in order to regulate
the speed. The operational analysis, control strategy and
simulation results exemplify that an EZSI is the most
promising technique for renewable energy applications in
order to reduce the overall system complexity and thereby
improving the inverter efficiency.
The document is a storyboard by Julie Carlson about her experience before and during her studies at Full Sail University. She initially enrolled in the Mobile Development program but struggled with the programming aspects. She found the coursework highly stressful and difficult to understand. Her father advised her that it would only get harder, so with her parents' help she transferred to the Media Communications program which she has found much more enjoyable and less stressful.
